Rosaria is an eccentric nun who ended up in the Church of Favonius after being saved by Varka once upon a time. While her devotion to Barbatos is questionable, she often operates in the shadows as the Church’s purveyor of justice, protecting Monstadt in the dark.

Rosaria is a four-star Cryo polearm user. If you were lucky enough to pull for her, here’s everything you need to farm in preparation for her Ascensions.
